The largest steel processing plant in the capital has been built and put into operation at the subway construction site

 

   The largest fully automatic numerical control steel bar processing plant in the history of Beijing Metro is also the strongest line-up in the capital. The intensive steel bar processing plant has been built and put into operation at the construction site of China Railway No.16 Engineering Group Co., Ltd., which has thoroughly innovated the traditional processing operation mode, with an annual production capacity of 5000 tons, which can meet the steel bar requirements of 3-5 subway projects.

Factory centralized processing mode

Today, a group of reporters walked into the processing plant, which is located in the South District Station of No.01 section of Beijing metro line 17, covering an area of about 2200 square meters, equivalent to the size of five and a half standard basketball courts.

Beijing Rail Transit Construction Management Co., Ltd. introduced the relevant person in charge, the company selected line 17 01 bid as the "steel processing factory" pilot. The project moved quickly, and the processing plant was completed and put into operation at the end of August this year. The "factory" centralized processing operation mode was adopted. Through advanced technology, equipment and management means, batch and assembly line construction was realized, which not only reduced the economic cost of the project, but also effectively improved the operation efficiency.

Reporters saw that the processing plant staff are busy welding steel grid. The huge processing plant is divided into more than ten areas, such as raw material stacking area, profile stacking area, semi-finished product processing area, profile processing area, mold setting area, processing area, finished product stacking area, etc., and obvious signboards are set up, with clear functional zoning and clean and tidy ground.

According to the person in charge, the whole processing plant adopts fully enclosed construction, which avoids the dust emission from the open-air welding, cutting and transportation of steel bars on site, and reduces the external noise impact to the minimum. At the same time, the processing plant also set up a number of welding fume dust collectors, the ceiling is covered with color steel plate interval sunlight plate, and set up ball fan, and the side wall is opened with glass window to ensure lighting and ventilation. "The project department adheres to the environmental protection management of sorting, rectifying, cleaning, literacy and safety, so as to create a clean and dust-free construction environment for workers, and comprehensively upgrade the green and civilized construction standards, and take care of the blue sky of the capital."

Centralized processing creates sharing platform

Why do we have to spend so much effort to build such a large steel processing plant? The person in charge said that in view of the general trend of green environmental protection, the development of rail transit requires the collection of Beijing's advantageous resources.

The main function of the processing plant is to concentrate on processing steel grille, small conduit and other reinforcement products used in the process of subway construction. Through efficient and standardized closed-loop management process and advanced CNC equipment, it can meet the reinforcement requirements of 3-5 metro projects.

He said that the steel processing plant will be gradually promoted in the city. China Railway 16th Bureau has 5 projects in Beijing. The establishment of such a large processing plant can meet the needs of various projects for reinforcement. Centralized processing of steel bars can also save raw materials and realize resource sharing.

At present, the processing plant has formed a closed-loop management process from steel raw materials to finished steel products and distribution. The processed steel bars can supply steel grids for Beijing metro line 17 bid No. 01, No. 10 bid No. 17 and No. 1 bid No. 3 of line 8. The preliminary total supply quantity will reach 7563 tons.

As the largest fully automatic numerical control steel bar processing plant in the history of Beijing Metro, the project department has introduced 13 large-scale automatic steel bar processing equipment, such as numerical control steel bar hoop bending machine, punching and shearing machine, small pipe tip forming machine, etc., which has thoroughly innovated the traditional processing mode, with a production capacity of 5000 tons / year.

In the process of numerical control processing, a team only needs 3 people to operate. Compared with the past, 7 labor forces are saved, and only labor cost is one construction. At least 252000 yuan of labor cost can be saved a year. After setting parameters and using computer control, cutting, bending and other processes of various steels can be "completed in one go", greatly improving the accuracy of steel products and reducing the loss of raw materials The error is avoided effectively.

"To implement factory management, in addition to high standards of resource allocation, we require zero defects in the quality of steel bars delivered from the factory, and the qualified rate of products can reach 100% every day." When it comes to the quality of steel products, the workers are full of confidence.
